{"schemaVersion":3,"id":"CVE-2026-110723","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In `api-gateway` versions till `1.7.3`, The default rate-limit key resolver, `ClientIpKeyResolver`, derives the per-client bucket key from the leftmost element of the `X-Forwarded-For` request header. That element is supplied by the originating HTTP client and is not validated against any trusted-proxy list. A single attacker can therefore obtain an unlimited number of independent rate-limit buckets — one per unique header value — and completely bypass the gateway's request-rate limiting on every route that uses the shipped default configuration.","dates":{"published":"2026-10-15T12:14:08.140Z","modified":"2026-10-15T13:11:12.574Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00337,"percentile":0.25562,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-16T00:00:00.000Z","score":0.00337,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00337,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00337,"percentile":0.25562}],"last30":[{"date":"2026-10-16T00:00:00.000Z","score":0.00337,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00337,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00337,"percentile":0.25562}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing","description":"This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.","type":"weakness","status":"Incomplete","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/290.html"},{"id":"CWE-644","name":"Improper Neutralization of HTTP Headers for Scripting Syntax","description":"The product does not neutralize or incorrectly neutralizes web scripting syntax in HTTP headers that can be used by web browser components that can process raw headers, such as Flash.","type":"weakness","status":"Incomplete","abstraction":"Variant","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/644.html"}],"affected":[{"vendor":"eclipse foundation","product":"eclipse connected services platform","name":"Eclipse Connected Services Platform","label":"eclipse connected services platform","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 1.1.1, ≤ 1.7.3","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 1.1.1, ≤ 1.7.3","eol":null,"hubHref":"/vendor/eclipse_foundation/eclipse_connected_services_platform"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/eclipse-ecsp/api-gateway/pull/330","label":"github.com/eclipse-ecsp/api-gateway/pull/330","hostname":"github.com","tags":[]},{"url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-m468-w7pr-f39w","label":"github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-m468-w7pr-f39w","hostname":"github.com","tags":[]},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/406","label":"gitlab.eclipse.org/security/cve-assignment/-/work_items/406","hostname":"gitlab.eclipse.org","tags":[]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T12:14:08.140Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T13:11:12.574Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":30,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T08:58:38.816Z","stale":false,"partial":false}}
